<p>PROBLEM TO BE SOLVED: To perform accurate balance correction of a rotating body in a short time.SOLUTION: A balance correction method corrects balance of a rotating body 214 by removing amounts of unbalance of a first correction surface 208a and a second correction surface 210a of the rotating body 214. For example, vibration of the rotating body 214 being in a rotating state is calculated before and after removal of the amount of unbalance of the first correction surface 208a, and amounts of unbalance of the first correction surface 208a and the second correction surface 210a are calculated on the basis of an influence coefficient defining a relation between an amount of unbalance of the rotating body 214 and the vibration of the rotating body, and the vibration of the rotating body, and the amount of unbalance of the first correction surface 208a is removed by a processing device, and it is determined whether the vibration of the rotating body 214 is a preliminarily set control value or less or not, and an influence coefficient for use in recalculation of the amount of unbalance is calculated backward on the basis of the vibration of the rotating body 214 before and after removal of the amount of unbalance if the vibration of the rotating body 214 is not the control value or less.</p> |
